Hi folks I'm Dick, 77 years old,live in Texas and bored with backyard birds & TV. I have some health issues that rein me indoors most of the time so have resorted to doing these puzzles to pass the time by.

I find that there is a solution as should be with effort and time but sometimes it takes me 2 to 3 hours to complete one,while others I just zip through. I use pure logic, in other words no trial and error, but I sometimes spend 15 to 20 minutes spotting and/or coming up with the path. I'm a little smarter than the average bear so why am I bogging down?

Yes, same with me. I play sudoku, I love it also but it takes time for me to complete it. Because I am slow.
